2 Claims. (Cl. 267-71) 3,110,486 Patented Nov. 12, 1963 views, thenumeral refers to an awning window which This invention relates toawning windows and is more N particularly directed to a vent link forawning window structure which permits the locking of the vents in theirclose-d position and the opening of a portion of the vents prior to theopening of all the vents.

The present application is acontinuation of application Serial No.23,166, filed on April 19, 1960, and now Pat. No. 3,070,853 patentedJanuary 1, 1963 and entitled Awning Window.

A principal object of the present invention is to provide an awningwindow with operating mechanism which causes the automatic locking ofthe vents when in their closed positions.

Another object of the present invention is to provide an awning windowwith a plurality of vents, the lowermost one of which is arranged toopen slightly while the other vents are still in their closed position.

A still further object of the present invention is to provide an awningwindow which assures the closing of all vents to their weather-tightposition even though the operating mechanism for any of them may beslightly out of adjustment without subjecting any of the operatingmechanism to any strain, undue wear or danger of buckling or fracturingof the various parts thereof.

A still another object of the present invention is to provide an awningwindow with vent links constructed of a pair of extensible membersslidably joined together and maintained in a compressed position by acoil spring which yieldingly permits the members to become eX- tended topermit the locking of the vents.

With these and other objects in view, the invention will be bestunderstood from a consideration of the fol lowing detailed descriptiontaken in connection with the accompanying drawings forming a part ofthis specification, with the understanding, however, that the inventionis not confined to any strict conformity with the showing of thedrawings but may be changed or modified so long as such changes ormodifications mark no material departure from the salient features ofthe invention as expressed in the appended claims.

In the drawings:

embodies my invention and consisting of a plurality of verticallyswinging vents 11 mounted on a frame 12 having stiles 18. Although theawning window 10' is shown having three vents 11 any number of vents 11may be used as desired determined by the over all height of the window10.

Along each of the stiles 18 of the frame 12 is a vertically disposedslide bar 13 maintained in a slidable position on the frame 11 by aplurality of brackets 14 which are secured to the inside wall of thestiles 18 by screws 15. At the forward end of the brackets 14 there isprovided a flanged portion 16 extending at approximately right angle tothe vertical side wall 18 of the frame 12 and whose function isdescribed in detail hereinafter.

Each of the vents 11 are provided with a pair of binge plates 19 securedat the top portion of each side of the vents 11 as by screws 17 with theends extending beyond the top edge of the vent and pivotally secured asat 20 to the slide bars 13. At the lower end of each of the hinge plates19 of all the vents 11 except the bottom vent there is a vent link 21whose upper end is pivotally mounted as at 23 to the vents 11 and theirlower ends extending rearwardly to an inner side wall 24 of the stile 18where the pivot link 21 is pivoted by a pivot pin 22. The bottom vent 11is provided with vent links 25 which are pivotally secured by the pivotpin 23 to the hinge plates 19 and at their lower ends to the side wall24 by the pivot pins 22. It can readily be noted that by means of theabove described construction when the slide bars 13 are made to slidedownwardly, the upper end of the vent links 21, 25 whose lower ends arepivotally secured to the frame wall 24 will swing outwardly anddownwardly as the x hinge plates 19 slide downwardly with the slide bars13. The vents 11 are caused to be brought to their open position asshown by FIGURE 2. To close the vents 1-1, the slide bars 13 are made toslide upwardly carrying the hinge plates 19 and causing the upper ends iof the vent links 21, 25 to swing upwardly and inwardly until the vents11 arrive at their closed position as shown by FIGURES 3 and 4.

Means are provided for operating the slide bars 13 in unison comprisingoperating links 27 each of whose i upper end is pivoted as at 28 to thelower end of the FIGURE 1 is a perspective view of an awning window Iconstructed in accordance with my invention.

FIGURE 2 is a longitudinal cross sectional view taken along the line 22of FIGURE 1.

FIGURE 3 is a similar view with the upper vents shown in their initiallyclosed position and the lowermost vent slightly opened.

FIGURE 4 is a similar view with all of the vents in their closed andlocked positions.

FIGURES 5 and 6 are transverse cross sectional views taken along thelines 55 and 66 respectively of FIGURE 4.

FIGURES 7 and 8 are enlarged fragmentary views of the vent links as theyappear in FIGURES 3 and 4 respectively. i

FIGURE 9 is a cross sectional view taken along the line 9-9 of FIGURE 7.

FIGURE 10 is a cross sectional View of my vent link taken along the line1010 of FIGURE 7.

Referring to the drawings wherein like numerals are used to designatesimilar parts throughout the several slide 'bars 13. The lower ends ofthe operating links 27 are secured to one end of a power arm 29 by apivot pin 30, the other end of the power arms 29 being secured to theends of a cross shaft 3-1. The extreme ends of the cross shaft 31 arejournalled in bearings (not shown) to permit the ready rotation of thecross shaft 31 and the consequent easy manipulation of the operator 32for opening and closing the vents 11. The operator 32 which is mountedon one side of the frame 12- is of conventional construction and isprovided with an operator arm 33 whose free end 35 is slidablypositioned in an elongated slot 34 in the power arm 29. As the operator32 is actuated the operator arm 33 is swung in an arc to cause the powerarm 29 to swing and the slide bars 13 in opening and closing the vents11 as aforementioned.

The structure discussed hereinabove is conventional and well known tothe art, but is one which requires a meticulous and constant adjustmentso that all of the vents will come to a tightly closed positionsimultaneously. If the vents -11 :did not close properly, then itsweather-tight efficiency would be low. Any attempt to bring a vent whichis opened. to a closed position when one or more of the other vents areclosed, will cause the various operating mechanism to become distorted,strained or broken and pivot pins to be sheared or gears becomingthreaded. Also, the vents of a conventionally constructed awning windowcannot automatically become locked upon closing.

Means are provided herein to assure the closing of all of the vents 11Whether or not the vents come to a closed position simultaneously andalso lock the vents 11 as they arrive at their completely closedposition consisting of the vent link 21 which is constructed of a pairof slidably mounted members 40 and 41. Each of the members 40 and 41 asprovided with an elongated slot 42 through which extends a pin 43 and44. The pin 43 is secured to the member 40' and extends through the slot42 in the member 41 while the pin 44 is secured to the member 41 andextends through the slot 42 of the member 40. Both of the pins 43 and 44are provided with a head for engaging the members 40 and 41 to compelthe parts to remain slidably together. The member 40 and 41 are alsoprovided with opposed openings 45 for receiving a coil spring 46, whichis retained therein by outwardly extending wall portions 47 at theposition of the openings 45.

The lowermost vent 11 is provided with the vent links 25 which are ofconventional single member construction. When the operator 32 isactuated to close the vents 11, the upper vents 11 will arrive at acontact position with the frame 12 While the lowermost vent 11 is stillin a slightly opened position as shown by FIG- URE 3. This permits aperson to open the lowermost vent 11 while maintaining the upper vents11 in their closed position, which is desirable during the cold orotherwise inclement weather. If it is decided to close all of the vents11, a further actuation of the operator 32 will cause the slide bar 13to slide upwardly carrying the hinge plates 19 and causing the vents 11to swing inwardly. Since the lowermost vent 11 had not yet arrived atits closed position, it will swing to its closed position. However,since the upper vents 11 were in their closed positions and cannot swinginwardly any further, the continued rotation of the operator 32 causesthe upper vents 11 to slide upwardly on the frame 12 by virtue of thevent links 21 which will expand in length against the coil springpressure 46. The members 40 and 41 will slide along each othercompressing the coil spring 46. As the vents 11 slide upwardly on theframe 12, a pin 50 which is mounted on each side of the vents 11, willslide upwardly to a position behind the flanged member 16 therebylocking the vents 11.

In opening the vents 11, as the operator 32 is actuated, the slide bar13 will immediately commence sliding downwardly. The links 21 which hadhad their respective coil springs 46 compressed during the lockingoperation will now permit the coil spring 46 to expand to its normalposition causing the vents 11 to slide downwardly and the pin 50 toslide to a position below the flange member 16. At the same time thelowermost vent 11 having the conventional vent link 25 will swing to aslightly opened position as shown by FIGURE 3 Since its vent link 25 isof solid construction after the springs 46 are back to their expandedcondition and the pins 43, 44 engage the outer edges of the slots 42,the links 21 then operate in the same manner as the links 25 and causethe vents lit to swing outwardly to their open position.
